GAINESVILLE, Fla. — Call them tattletale pills.
Seeking a way to confirm that patients have taken their medication, University of Florida engineering researchers have added a tiny microchip and digestible antenna to a standard pill capsule. The prototype is intended to pave the way for mass-produced pills that, when ingested, automatically alert doctors, loved ones or scientists working with patients in clinical drug trials.
“It is a way to monitor whether your patient is taking their medication in a timely manner,” said Rizwan Bashirullah, UF assistant professor in electrical and computer engineering.
Such a pill is needed because many patients forget, refuse or bungle the job of taking their medication. This causes or exacerbates medical problems, spurs hospitalizations or expensive medical procedures and undercuts clinical trials of new drugs.
The American Heart Association calls patients’ failure to follow prescription regimens “the number one problem in treating illness today.” Studies have found, for example, that patients with chronic diseases normally take only about half their prescribed medications. According to the American Heart Association, 10 percent of hospital admissions result from patients not following the guidelines on their prescriptions. Other studies have found that not taking medication properly results in 218,000 deaths annually.
